One issue you may wish to consider.
4.3.3
Navigator implements NavigatorDoNotTrack;Objects implementing the
Navigator interface [NAVIGATOR] (e.g., the window.navigator object) must
also implement the NavigatorDoNotTrack interface. An instance of
NavigatorDoNotTrack is obtained by using binding-specific casting methods
on an instance of Navigator.
How does JavaScript know if the DOM property was set by the default at
install time or was set by an on-screen "User Choice" or was set by a 3rd
Party?
Punting this over to "public opinion, criticism, action on the part of
servers etc.," could be cause for content providers to simply ignore the
spec. It's not their job to define it, it's their job to implement it.
